Background technology
All the time, the stability of side slope is a major issue in civil engineering always, and slope instability can cause life and property loss, or even security incident, and bolt support is a kind of relatively more conventional reinforcing side slope technique.In order to obtain the anchored force of anchor pole, judging anchor pole performance, usually needing to do the test of side slope anchor rod drawing at the scene.Side slope is carried out anchor rod drawing test with conventional test unlike, anchor pole is fixed in side slope through jack, the deadweight of jack be can not ignore, not easily fix in process of the test, also can produce larger eccentric force to anchor pole, experimental data is affected, even hinders the carrying out of test.Especially broken in some soil properties, in the side slope of poor stability, jack directly acts on side slope can produce larger displacement deformation because of larger tension stress, larger on the impact of test accuracy.
Summary of the invention
In view of this, the purpose of this utility model is to provide a kind of side slope anchor rod drawing to test counterforce device, utilizes this device can overcome the impact of jack deadweight on anchor pole, thus obtains reliable experimental data.
The purpose of this utility model is achieved through the following technical solutions:
A kind of side slope anchor rod drawing test counterforce device, comprise backing plate, the jack be arranged on backing plate, through backing plate and jack anchor pole, be arranged on anchor pole for backing plate and jack being fixed on the connector in side slope, also comprise concrete embedded heap and the support for fixing jack, described concrete embedded heap is arranged on below backing plate, described support is fixed on concrete embedded heap, and described concrete embedded heap is provided with the pre-buried through hole that diameter is greater than bolt diameter.
Further, also bed course is provided with between described connector and jack;
Further, state support and comprise base and be arranged on the jack supports on base, described base is fixed on concrete embedded heap;
Further, described base is two crossbeams, and described jack supports comprises and is arranged on two vertical beams on crossbeam and the gusset for being connected two vertical beams;
Further, described crossbeam is provided with the U-type groove for changing crossbeam and vertical beam link position;
Further, described jack supports also comprises pull bar, and described pull bar two ends are separately fixed on crossbeam and vertical beam, and described crossbeam and pull bar junction are provided with the U-type groove changing crossbeam and draw rod positions;
Further, described jack supports is provided with the rope for being fixed on by jack on support.
The beneficial effects of the utility model are:
Side slope anchor rod drawing test counterforce device of the present utility model, structure is simple, can overcome the eccentric force because jack deadweight produces anchor pole, improve the accuracy of experimental data; The scope of application is large, is applicable to the side slope of different angles, is also applicable in anchor pole and side slope angle different tests.
Other advantages of the present utility model, target and feature will be set forth to a certain extent in the following description, and to a certain extent, based on will be apparent to those skilled in the art to investigating hereafter, or can be instructed from practice of the present utility model.Target of the present utility model and other advantages can be realized by manual below and obtain.
Accompanying drawing explanation
In order to make the purpose of this utility model, technical scheme and beneficial effect clearly, the utility model provides following accompanying drawing to be described:
Fig. 1 is the utility model embodiment structural representation;
Fig. 2 is Fig. 1 medium-height trestle structural representation;
Fig. 3 is Fig. 2 medium-height trestle one-sided configuration schematic diagram.
Detailed description of the invention
Hereinafter with reference to accompanying drawing, preferred embodiment of the present utility model is described in detail.Should be appreciated that preferred embodiment only in order to the utility model is described, instead of in order to limit protection domain of the present utility model.
The side slope anchor rod drawing test counterforce device of the present embodiment as shown in Figure 1, comprise concrete embedded heap 1, anchor pole 3, backing plate 4, jack 6, connector 8, support 10, concrete embedded heap 1 is embedded in side slope 9, backing plate 4 is arranged on concrete embedded on 9, jack 6 arranges over the mount 10, support 10 is fixed on concrete embedded heap 1, described concrete embedded heap 1 is provided with the pre-buried through hole being greater than anchor pole 3 for diameter, anchor pole 3 one end is embedded in the ground of side slope 9, the other end successively through concrete embedded to 1 pre-buried through hole, backing plate 4, support 10, jack 6, anchor pole 3 is provided with connector 8, by regulating connector 8, jack 6 is fixed in side slope 9.In the present embodiment, because the deadweight of jack 6 all acts on over the mount 10, make the deadweight of jack can not produce eccentric force to anchor pole, thus improve the accuracy of experimental data, simultaneously, pre-buried through hole and side slope angle in concrete embedded heap 1 can be changed according to test demand, thus be applicable in the anchor pole test different from side slope angle.
In the present embodiment, support 10 is fixed on concrete embedded heap 1 by embedded bar 2, and the pre-buried end of embedded bar 2 is provided with hangnail, and the other end is provided with nut 5 and screw thread.
In the present embodiment, as shown in Figure 2, support 10 comprises base 10a and is arranged on the jack supports 10b on base, on the pre-buried heap 1 of base 10a fixing concrete, base 10a is two crossbeams 11, jack supports 10b comprises and is vertically set on two vertical beams 12 on crossbeam 11 and the gusset 13 for being connected two vertical beams, and described crossbeam 11 and vertical beam 12 are bolted.
As the improvement of the present embodiment; bed course 7 can be set between described connector 8 and jack 6, make the coupling mechanism force of connector first act on bed course 7, then act on jack 6 by bed course 7; the coupling mechanism force that jack is subject to is more even, plays a protective role to jack.
As the improvement of the present embodiment, as Fig. 3, crossbeam 11 is provided with for bolted U-type groove, by changing bolton position, vertical beam 12 can be moved on crossbeam 11, that is can, by jack 6 relative to the position of anchor pole 3, the centre bore of jack 6 not contacted completely with anchor pole 3, avoid because jack centre bore contacts the eccentric force produced with anchor pole further, improve measuring accuracy.
As the improvement of the present embodiment, as Fig. 3, described jack supports 10b also comprises pull bar 14, and described pull bar two ends are respectively by being bolted on crossbeam 11 and vertical beam 12, and described crossbeam and vertical beam and pull bar junction are provided with U-type groove.By arranging pull bar, make to form triangular structure between crossbeam, vertical beam, pull bar, make the structure of support more stable, what jack was more firm is fixed on support, by arranging U-type groove, vertical beam 12 can on crossbeam 13 position adjustable.
As the improvement of the present embodiment, jack supports 10b can be provided with rope, utilize rope to be wound around jack 6, more stable for jack 6 can be fixed on support.
What finally illustrate is, above preferred embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model by above preferred embodiment, but those skilled in the art are to be understood that, various change can be made to it in the form and details, and not depart from the utility model claims limited range.
